Are you some kind of superhuman? Even if you try really hard and aim precisely, as soon as the air turns on your hands get pushed to one side because the pressure is not exactly the same in both sides.
I use these all the time (they’re pretty much everywhere in the U.K.) and haven’t experienced this unbalanced pressure issue. They always seem pretty much equal pressure on each side to me.

With large hands, there's an extra degree of difficulty to avoid touching the sides and the bottom. It still leaves you with wet wrists and damp fingers.
